IMPROVEMENT IN HOSE.

Specification forming part of Letters Patent No. 123,365, dated February6, 1872.

I, JOSEPH SHARP, of Cincinnati, Hamilton county, State of Ohio, haveinvented a certain new and useful Improvement in Leather Hose, of whichthe following is a specification:

Nature and Object of Invention.

My invention consists of a new construction of leather hose, by whichthe joints are formed spirally both lengthwise and crosswise of thesheets of leather of which the hose is formed, the purpose and effectbeing to give greater strength with a given thickness of leather andform all the joints without waste of material.

Description of the Accompanying Drawing.

General Description.

The sheets of leather necessary to form my improved spiral-joint hoseare cut of the shape shown in Fig. 3, the width and length being such asto use the material to the best advantage. The form being rectangularand not beveling, like the old form, at the end, there is no waste ofmaterial in the construction of the hose. The sheets are bent spirallyas shown at Fig. l, and connected by rivets a both at the sides and endsof the sheets without any corner joints being occasioned or waste ofmaterial rendered necessary. In the old construction of hose having alongitudinal seam throughout its entire length it is necessary that theends of the sheets be cut beveling and the material be thus wasted inorder to avoid the cornerjoints, which are difficult to make tight andin] possible to avoid if the sheets are cut square at the ends. Theformation of the ordinary hose is illustrated in Fig. 4, the inclinedcut of the sheet causing an overlap which avoids the corner-joint.

Hose constructed in accordance with my improvement will possess greaterstrength for a given thickness of material than if made like Fig. 4, asI have conclusively proved by careful experiments; and, in addition tothis advantage, has the additional one of protection to the hose byhaving rivet-heads to rest upon the ground in all directions.

Claim.

A riveted hose, composed of sheets of leather or other suitablematerial, the sides of which are cut parallel and their ends at a rightangle to their sides in order that when their edges are rivetedtogether, as shown, the joints shall be formed spirally both lengthwiseand crosswise of the sheets, for the purpose specified.

In testimony of which invention 1 hereunto set my hand.
